I am trying to update the IOS image on a Cisco 3750-24T-S V03 switch from 12.2<50>SE3 to 12.2<55>SE5 using the TFTP procedure in Document ID: 41541. I have successfully updated other 2900, 3000, 3500 and 3600 switches using this procedure. But when attempting to perform the update on a 3750, I get more error "0" indications than success "!" indications during the transfer and the transfer times out. I have checked the flash, and I should have more than enough room to perform the transfer.
Is there another procedure that applies to the 3750 or are there other issues I should be aware of? I have searched the Cisco support site, but haven't found anything useful.
Agreed.just wanted to make sure there is no latency or some connectivity problems between your switch and
Make sure that speed/duplex settings are correct (if your workstation is a Windows box, it's very likely to have auto-negotiation turned on, while switch might be explicitly configured for 100Mbps/full-duplex operations).
Also, does your tftp server indicate that the initial tftp transfer begins and then ends prematurely.?
what is your file size.Side by side Can you please paste output of
Thanks for your help, but it turned out that it wasn't a switch issue alltogether. It turned out that the 3750 just did not want to play nice with the tftp app I was using. Not sure why, because it worked for my 2950, 3000, 3550, and 3650 switches. Not completely sure it is all the app's fault either, so I won't name it.
Switched to SolarWinds tftp server app and all is good.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
